I have a Cisco switch with surplus 40GbE ports (QSFP+). I am planning on getting Mellanox ConnectX-5 cards for some servers due to MLX ConnectX-3 cards going EOL for VMware. Is a QSFP+ 40GbE DAC supported between these devices? How about a QSFP28 DAC so we can future-proof the interconnect? I know that optics are generally backwards compatible (QSFP+ transceiver in QSFP28 port), but there isn't a lot of documentation on using copper.
